<p>one of my friends here just told me that her physics (I think, maybe chem) professor was really excited that the test he wrote made a perfect bell curve. Problem for the students: The median was a 60. Your B- is a lot better than a 27% that doesn't get curved.</p>
<p>in short, it's fine. You will get some grades that are a B- or worse. Move on, it's ok.</p>
